ANTIGLARE SHEELD FOR L-IEADLAMPS.

Application filed January 15, 1925. Serial 130. 81,414.

The object of this invention is to provide an improved anti-glare shield for automobile head lamps and the like.

A further object of this invention is to provide an anti-glare shield for head lamps that will fit any size 01' head lamps and may be attached or detached in a moments time without harm to the lamp.

A further objectis to provide an anti-glare shield that is simple in construction and eco nomical in manufacture.

liore specifically the object of this invention is to provide an anti-glare shield de signed to be mounted on the electric light socket of the lamp and to outwardly and forwardly extend therefrom in vertical steps.

A further object is to provide a means for keeping the steps in vertical position.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of my complete anti-glare shield ready for use.

Fig. 2 is a frontview' of my ed on a head lamp.

Fig. 3 is a top plan sectional view of my device mountdevice mounted on a head lamp and is taken on line 33 of Fig. 2.

any accidents fatal to life and property are caused by blinding head lamps. Devices now on the market for preventing the blinding light are costly and are confined chiefly to the construction of the lens of the lamp which are easily broken. My device deals with the reflecting of the light and is stamped from one piece of inexpensive sheet metal.

I have used the numeral to designate the bowl or body portion of an electric lamp, having the lens 11 and reflector 12. Mounted in the bowl 10 and extending through a hole 13 in the reflector 12 is the electric light socket 1 1 having lead wires 15 and 16. Mounted in this socket and in front of the reflector 12 is the incandescentlight bulb 17. I have designated my anti-glare'shield generally by the number 18. It is almost circular except for two large notches in its sides. These notches are diametrically opposite one from the other. In the center of diffuses and sprays the light.

my device is ahole 19 which is designed to embrace the socket 1%. From this socket my device extends outwardly and forwardly in vertical steps until the ends or ears 20 and 21 engage the reflector 12. its these ends are rounded they are capable of conforming to the curvature of the reflector and thereby make proper engagement therewith. This engagement is not essential but does act to stabilize the device in the lamp. (in lan'ips that have very large reflectors the ends would not perhaps touch the reflector at all. As before stated the device ing stamped from a piece of sheet metal and in so doing it is well to leave two tongues 22 and 23 extending into the hole 19. These tongues are designed to be bent around the marginal edge at the hele 13 in the reflector 12, as shown in Fig. 3. They aid in holding the shield in the lamp and prevent the same from turning from the position shown in Fig. 2. From this figure it will be noted that the two notches before mentioned directlyabove and below the bulb 1T, reset-etive'iy, or in other words the shield becomes larger as it extends laterally from the bulb 17. Neither the outwardly and rearwardlv extending walls 2.4L- or the forwardly and out wardly extending walls 25 that make up the steps are parallel with the axis of the bulb 17, but are at an angle thereto, as will be noted in Fig. 3. As the shield is in front of the reflector 12 and is preferably polished or nickled it becomes a reflector, but because of the steps it does not reflect the light as the reflector 12 into a tocus or spot of light, but T his however is not true when in a direct line in front oil? the bulb 17 as the shield is restricted. at its center and therefore does not shield ewe r flector 12 just above and'bclow the bulh 1' By this arrangement there is a condensed spray of light directly in front of the lamp. but a few degrees on eitherside of this condensed light, the shield becomes the reflector and the light is diffused and not blinding. This means that when automobiles use my invention and when passing each stays on its side of the road, respectively, and are not in direct line, there will be no blinding lights to affect the drivers of the automobiles Another advantage of my invention resides in the fact that it throws a glow of light to the side so that the driver can see pedestrians at the intersection of streets.

is capable of bc- To remove my device from the lamp, remove the bulb 17 and unbend the tongues 22 and 23.

Some changes may be made in construction and arrangement of my improved antiglare shield for head lamps without departing from the real spirit and purpose out my invention and it is my intention to cover by my claims and modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

ll claim:

1. In a device of the class described, a plate member having a hole near its center designed to embrace the electric light socket in a head lamp, vertical steps on said plate member, said plate member having a v' notch in its upper portion and a V notch in its lower portion, for the purposes stated.

2. In combination with a head lamp, a device comprising a plate having a hole designed to embrace the electric light socket in the said lamp, outwardly and forwardly extending walls formed on said plate, said plate member having a V notch in its upper portion and a V notch in its lower portion.

3. In a device of the class described, a plane central body portion having a hole, forwardly and utwardly extending walls on each side of said central portion, outwardly and rearwardly extending walls on each side of said central portion; said forwardly and outwardly extending walls being alternated with said outwardly and rearwardly extending walls, and tongues for holding the device to the reflector of a head lamp.

i. In a device of the class described, a plane central body portion having a hole,

forwardly and outwardly extending walls on each side of said central portion, outwardly and re'arwardly extending walls on each side 01 said central portion; said for wardly and outwardly extending walls being alternated with said outwardly and rearwardly extending walls, and said walls terminating on each side of said central portion in a circular marginal edge designed to engage the reflector of a head lamp.

5. In combination with a head lamp having a reflector and an electric light socket extending through a hole in said reflector, a device comprising a central body portion having a hole designed to embrace said socket, tongues on the marginal edge of said hole in the central body portion for embracing the marginal edge of the hole in said reflector. torwa 'dly and outwardly extending wallsv on each side of said central portion, outwardly and rearwardly extending walls on each side 01" said central portion, said outwardly and rearwardly extending walls being alternated with said forwardly and outwardly extending walls, said walls nearest said central portion being shorter in length than those more remote, and a flange having a circular marginal edge formed on the last extending wall on each side of the central body portion designed to contornr to and engage the inside of the said reflectorv 6. As a new article oi manufacture, an anti-glare shield for headlights coinpris' g a plane body portion and integral wings extending laterally therefrom and formed with successive steps vertically arranged right angles to each other and oblique to the axis of the headlight.
